mxnet.gluon.model_zoo.vision.BottleneckV1

class mxnet.gluon.model_zoo.vision.BottleneckV1(channels, stride, downsample=False, in_channels=0, **kwargs)[source]

Bottleneck V1 from “Deep Residual Learning for Image Recognition” paper. This is used for ResNet V1 for 50, 101, 152 layers.

Parameters
  • channels (int) – Number of output channels.

  • stride (int) – Stride size.

  • downsample (bool, default False) – Whether to downsample the input.

  • in_channels (int, default 0) – Number of input channels. Default is 0, to infer from the graph.

__init__(channels, stride, downsample=False, in_channels=0, **kwargs)[source]

Initialize self. See help(type(self)) for accurate signature.

Methods

__init__(channels, stride[, downsample, …])

Initialize self.

apply(fn)

Applies fn recursively to every child block as well as self.

cast(dtype)

Cast this Block to use another data type.

collect_params([select])

Returns a ParameterDict containing this Block and all of its children’s Parameters(default), also can returns the select ParameterDict which match some given regular expressions.

export(path[, epoch])

Export HybridBlock to json format that can be loaded by SymbolBlock.imports, mxnet.mod.Module or the C++ interface.

forward(x, *args)

Defines the forward computation.

hybrid_forward(F, x)

Overrides to construct symbolic graph for this Block.

hybridize([active])

Activates or deactivates HybridBlock s recursively.

infer_shape(*args)

Infers shape of Parameters from inputs.

infer_type(*args)

Infers data type of Parameters from inputs.

initialize([init, ctx, verbose, force_reinit])

Initializes Parameter s of this Block and its children.

load_parameters(filename[, ctx, …])

Load parameters from file previously saved by save_parameters.

load_params(filename[, ctx, allow_missing, …])

[Deprecated] Please use load_parameters.

name_scope()

Returns a name space object managing a child Block and parameter names.

register_child(block[, name])

Registers block as a child of self.

register_forward_hook(hook)

Registers a forward hook on the block.

register_forward_pre_hook(hook)

Registers a forward pre-hook on the block.

save_parameters(filename)

Save parameters to file.

save_params(filename)

[Deprecated] Please use save_parameters.

summary(*inputs)

Print the summary of the model’s output and parameters.

Attributes

name

Name of this Block, without ‘_’ in the end.

params

Returns this Block’s parameter dictionary (does not include its children’s parameters).

prefix

Prefix of this Block.
